Hello!

I have the following scenario: given a list of codes in a CSV file, execute the scenario with each value from the feeder sequentially one-by-one. I.e., I don’t need to load the service under test with a certain number of users during a certain period of time. Just execute the same scenario with each value from the feeder. My goal is to measure the response time of the service.

Until now, I made the following scenario configuration:

`

```auto
setUp(scn.inject(constantUsersPerSec(1) during (30 seconds))).protocols(httpConf)

```

`

My feeder has 30 values, so I execute one value per second. But I’m not sure if this configuration is suitable for my scenario. Could you please advise what simulation configuration can I use for my goal?
